Minnesota Post Bulletin on the Nietzsche Nachlass
The archive became a hub for the nascent National Socialist (Nazi) Party as Elisabeth appointed its ideologues to editorial and administrative posts. Alfred Baeumler — who would later supervise production of textbooks presenting theories of race and blood as fact, support the Nazification of the universities, and oversee the Berlin book burning — prepared Nietzsche’s texts for new editions. Martin Heidegger was a member of the Nazi Party when he joined Baeumler as editor in the archive. Together, they took the extraordinary view that Nietzsche’s previously published works hardly counted; his real philosophy resided in the other papers and literary fragments already manipulated by Elisabeth, which they would further distort.
I'm surprised Heidegger and Baeumler cooperated on anything.
